Architect for a Roof Raise

Is your home becoming too small? A roof raise — or vertical extension — could be the ideal solution to increase your home's living area. Whether to accommodate a growing family or to make up for purchasing a property that is too small, the reasons homeowners choose this option are many.

Whatever the case, a roof raise offers the possibility of adding extra square footage without sacrificing a terrace or garden, as is sometimes the case with a traditional side extension.

However, raising the roof is a complex undertaking that requires the involvement of a specialist architect in this field.

Why is it advisable to hire a specialist architect for a roof raise?

Having an architect on board is a major asset, as raising the roof is far more involved than adding a ground-level extension to a terrace.

This type of work means touching the very structure of the building and carefully analysing the original construction to determine whether the addition is feasible. The foundations and load-bearing walls must be able to support the additional structure — or will need to be reinforced.

Here are the main reasons to call on a specialist architect for a roof raise:

Technical constraints involved in the works
A roof raise is an increasingly sought-after solution in high-density urban areas, where horizontal construction is difficult. However, it requires a feasibility study and depends heavily on the quality of the existing foundations and structure. A soil survey is also necessary to ensure the long-term durability of the new construction. A specialist architect in roof raises has the knowledge and expertise required to successfully carry out this type of project.

Compliance with current regulations
A specialist architect in roof raises is well-versed in the regulations applicable in each region of France. Maximum height, number of permitted storeys — there are strict rules governing how high a property can be raised. A precise set of specifications must be adhered to.
An architect saves you valuable time by thoroughly assessing your project and proposing a plan that complies with the rules of your town or municipality.

Professional guidance in redistributing space
Following a roof raise, it is sometimes necessary to rethink the layout of your home. While the existing spaces may remain unchanged, it can be necessary to modify them — for instance, to add a staircase or relocate certain rooms, such as bedrooms, to the newly created upper level.
An architect advises and supports their clients in arranging the new spaces, with the aim of creating a home that is both practical and pleasant to live in.
